The order of reactivity of halogens towards hydrogen is

What is the order of reactivity of alkali metals towards hydrogen?

Consider the following chlorides: The order of reactivity of A, B,C and D towards hydrolysis by S_(N)1 mechanism is :

The order of reactivity of halogens with methane is

Order of reactivity of halogen acids towards an alcohol is: (HCl,HBr,HI)

The order of reactivity of halides towards S_(N) 1 mechanism is

Order of reactivity of hydrogen halides towards ethers is

Order of reactivity of alcohols towards sodium metal is

In general the order of reactivity of halogens with transition metals is

The order of reactivity of various alkyl halides towards nucleophilic substitution follows the order
